Not sure about the laptop only or not.  I did enough research to be able to
tell if my PC was capable of the wireless display feature, and bought it.  I
am not a big fan of wireless A/V over wired, however in my case it was a need
and the only way to accomplish it without expensive hubs.   

I have wired outdoor speaker planters, to an older Onkyo receiver, and
muti-room switcher.  It's connected to an airport express and itunes.  Prior
to the airport express it was a 200 disc CD changer. Lets just say that the
wiring was a lot of work to get it from the second floor of my home to the
back yard, and frankly I couldn't hear the difference between
itunes versus the 200 disc changer as the outdoor speakers were a garage sale
find and crap anyway :)  Since then I'm more open to wireless tech -- except
for my home theater system.  

After owning the Miracast/Microsft WD for a few weeks now, the only minor
annoyance is having to reconnect it (in monitor settings) each time Windows
reboots.  Otherwise I've noticed zero difference between it and the HDMI hard
connected display.
